[0033] First Embodiment

[0034] Please refer to the reference. Figures 1 to 6 This invention provides a wearable breast pump 100 for expressing breast milk. It simplifies the assembly and disassembly process, saves time and effort, improves assembly and disassembly efficiency, facilitates breast pumping, and enhances the user experience.

[0035] The wearable breast pump 100 includes a bra 110, a suction bowl 120, a one-way airflow guide 130, a milk bowl 150, and a suction mechanism 160. The suction bowl 120 and the bra 110 are integrally formed, and the bra 110 cooperates with the milk bowl 150. The bra 110, the suction bowl 120, and the milk bowl 150 together form a breathing cavity 170. The suction mechanism 160 is connected to the breathing cavity 170 and is used to extract air from the breathing cavity 170 to create a negative pressure in the breathing cavity 170, thereby causing the suction bowl 120 to elastically deform. When the suction mechanism 160 stops working, the suction bowl 120 will spring back to its original position under its own elastic force and draw outside air into the breathing cavity 170. The milk bowl 150 and the breast shield 110 together form a storage cavity 180. The suction bowl 120 is designed to elastically deform under the suction force of the suction mechanism 160, creating a negative pressure inside the breast shield 110 and drawing out milk. The breast shield 110 is connected to the storage cavity 180 via a one-way flow guide 130, which allows milk to flow into the storage cavity 180 and also prevents milk from flowing back into the storage cavity 180. Because the suction bowl 120 and the breast shield 110 are integrally molded, the number of parts is reduced, effectively simplifying the assembly and disassembly process of the wearable breast pump 100, improving assembly and disassembly efficiency, and facilitating assembly for milk expression and disassembly for cleaning.

[0036] The bra 110 includes an integrally formed connecting ring 111 and a fitting cup 112. A suction bowl 120 is disposed at the end of the connecting ring 111 away from the fitting cup 112 and is integrally formed with the connecting ring 111. The bra 110 and the suction bowl 120 are made of flexible material.

[0037] In one alternative embodiment, the unidirectional flow guide 130 is integrally formed with the connecting ring 111 and is disposed between the suction bowl 120 and the fitting cup 112. The connecting ring 111 is connected to the storage cavity 180 through the unidirectional flow guide 130 to realize the unidirectional milk dispensing function.

[0038] In this embodiment, the unidirectional flow guide 130 is a one-way valve. In other embodiments of the present invention, the unidirectional flow guide 130 may also be a one-way diaphragm or other structure with unidirectional transmission capability, and its specific structural type is not limited.

[0039] Preferably, the outer wall of the connecting ring 111 is provided with a sealing boss 116, and the milk bowl 150 is provided with a sealing groove 151. The sealing groove 151 is annular, and the sealing boss 116 cooperates with the sealing groove 151 to seal the breathing cavity 170, prevent air leakage, and ensure the airtightness of the breathing cavity 170. In addition, the cooperation between the sealing boss 116 and the sealing groove 151 can also play a limiting role to fix the relative position of the connecting ring 111 and the milk bowl 150, and prevent the connecting ring 111 from being misaligned within the milk bowl 150.

[0040] It should be noted that the end of the fitting cup 112 away from the connecting ring 111 is provided with a flange groove 117, which is annular. The end of the milk bowl 150 is provided with a mating boss 152. The mating boss 152 mates with the flange groove 117 to fix the relative position of the milk bowl 150 and the fitting cup 112, thereby fixing the relative position of the milk bowl 150 and the entire bra 110, and realizing the assembly function of the milk bowl 150 and the bra 110.

[0041] Furthermore, the cup 112 is provided with a handle 118, which is used by a person to pull to disengage the mating boss 152 and the flange groove 117, thereby realizing the disassembly function of the milk bowl 150 and the bra 110 for easy cleaning. Specifically, the handle 118 is in the shape of a sheet or ring and has a small area to facilitate the application of force and not affect human comfort.

[0042] Preferably, the cup 112 has a first milk outlet groove 119, and the bowl 150 has a second milk outlet groove 153. The first milk outlet groove 119 and the second milk outlet groove 153 together form a milk outlet 190, which communicates with the storage cavity 180 and is used to pour out the milk in the storage cavity 180. Specifically, the milk outlet 190 is located at the top of the entire wearable breast pump 100, that is, the first milk outlet groove 119 is located at the top of the cup 112, and the second milk outlet groove 153 is located at the top of the bowl 150, to ensure that the milk does not flow out during the filling of the storage cavity 180. After pumping, the wearable breast pump 100 is removed and inverted to pour out the milk in the storage cavity 180 through the milk outlet 190, which is convenient and practical.

[0043] Preferably, the handle 118 and the first milk outlet 119 are positioned opposite each other at both ends of the cup 112, with the first milk outlet 119 located at the top of the cup 112 and the handle 118 located at the bottom. This allows for quick and easy disassembly of the milk bowl 150 and the bra 110; one hand can pull the handle 118 while the other hand reaches into the milk outlet 190 to pry open the first milk outlet 119 and the second milk outlet 153.

[0044] In one optional embodiment, the suction mechanism 160 includes a housing 161 and a circuit board 162, a solenoid valve 163, an air pump 164, and an air tube 165 installed within the housing 161. The circuit board 162 is connected to the air pump 164 via the solenoid valve 163, and the circuit board 162 can control the air pump 164 to start or stop via the solenoid valve 163. Specifically, one end of the air tube 165 is connected to the air pump 164, and the other end is connected to the breathing cavity 170. When the air pump 164 is started, the air pump 164 can draw air out of the breathing cavity 170 through the air tube 165 to achieve a negative pressure milk suction function.

[0045] In an alternative embodiment, the suction mechanism 160 further includes a battery 166, which is installed inside the housing and is electrically connected to the circuit board 162, the solenoid valve 163 and the air pump 164. The battery 166 is used to supply power to the circuit board 162, the solenoid valve 163 and the air pump 164.

[0046] In one optional embodiment, the milk bowl 150 has a notch 154, and the suction mechanism 160 is installed in the milk bowl 150 and disposed within the notch 154, that is, the suction mechanism 160 is embedded in the notch 154. The suction mechanism 160 and the milk bowl 150 together form a dome shape to improve the integrity and aesthetics of the wearable breast pump 100. Specifically, the outer shell 161 of the suction mechanism 160 is detachably connected to the milk bowl 150 to facilitate assembly for milk expression and disassembly for cleaning.

[0047] In one alternative embodiment, both the milk bowl 150 and the outer shell 161 are made of plastic material, which has high strength and low density, enabling the wearable breast pump 100 to be lightweight, easy to assemble and disassemble, and improve the user experience.

[0048] In some embodiments, a liner 140 adapted to the bra 110 is also provided. Specifically, the liner 140 is installed inside the bra 110 and is located on the side of the suction cup 120 away from the breathing cavity 170. The liner 140 is connected to the storage cavity 180 through a one-way flow guide 130. The liner 140 is designed to fit against the breast and allow the nipple to extend into it. The suction cup 120 is designed to elastically deform away from the liner 140 under the suction force of the suction mechanism 160, so as to create a negative pressure inside the liner 140 and draw out the milk.

[0049] Furthermore, the inner liner 140 is installed inside the connecting ring 111, which is used to limit and fix the inner liner 140 to prevent it from falling out. The fitting cup 112 is used to fit the breast to improve airtightness and ensure that a stable negative pressure is formed inside the inner liner 140 when pumping milk.

[0050] In one optional embodiment, the unidirectional flow guide 130 is integrally formed with the connecting ring 111, and the inner liner 140 has a relief groove 142 that communicates with the unidirectional flow guide 130. The milk sucked out of the inner liner 140 can flow sequentially through the relief groove 142 and the unidirectional flow guide 130 to the storage cavity 180. Specifically, the unidirectional flow guide 130 is disposed on the lower side wall of the connecting ring 111, that is, the breast shield 110, the suction bowl 120, and the unidirectional flow guide 130 are integrally formed to further reduce the number of parts, simplify the disassembly and assembly process, and improve disassembly and assembly efficiency.

[0051] Furthermore, the bra 110, suction bowl 120, and one-way flow guide 130 are all made of silicone material, which has a certain degree of elasticity, enabling it to perform the milk expression function and providing good comfort. In other embodiments of the present invention, the bra 110, suction bowl 120, and one-way flow guide 130 may also be made of other flexible materials, and there is no limitation on the specific material type.

[0052] In one optional embodiment, the one-way flow guide 130 can also be separately provided from the bra 110 and detachably installed on the connecting ring 111 of the bra 110; in another optional embodiment, the one-way flow guide 130 can also be installed on the liner 140 or integrally formed with the liner 140. In this case, the bra 110 has a relief groove, which communicates with the one-way flow guide 130. The milk sucked out of the liner 140 can flow to the storage cavity 180 through the one-way flow guide 130 and the relief groove in sequence.

[0053] Preferably, the inner wall of the connecting ring 111 is provided with a guide groove 113, which extends along the axial direction of the connecting ring 111. The inner liner 140 is provided with a slide 143, which slides in cooperation with the guide groove 113. The slide 143 can slide relative to the guide groove 113, and the guide groove 113 can guide and limit the slide 143 to ensure that the inner liner 140 can only cooperate with the connecting ring 111 along the axial direction of the connecting ring 111, and to prevent the inner liner 140 from rotating relative to the connecting ring 111.

[0054] Furthermore, the inner wall of the connecting ring 111 is provided with a groove 114, which is annular. The inner liner 140 is provided with a locking platform 144, which engages with the groove 114 to fix the relative position of the connecting ring 111 and the inner liner 140, preventing the inner liner 140 from accidentally detaching from the connecting ring 111. Specifically, the groove 114 is located between the guide groove 113 and the suction cup 120. When the inner liner 140 slides relative to the guide groove 113 to a preset position, the locking platform 144 engages with the groove 114. In this way, on the one hand, the groove 114 can limit the locking platform 144 to fix the relative position of the connecting ring 111 and the inner liner 140; on the other hand, since the groove 114 is annular, the engagement of the locking platform 144 and the groove 114 can provide a sealing effect, preventing air leakage and ensuring airtightness.

[0055] Furthermore, the connecting ring 111 is provided with a stepped surface 115, and the guide groove 113 is provided between the slot 114 and the stepped surface 115. When the inner liner 140 slides relative to the guide groove 113 to a preset position, the inner liner 140 abuts against the stepped surface 115. At this time, the stepped surface 115 can limit the inner liner 140 to prevent the inner liner 140 from continuing to slide into the guide groove 113, thus playing a role in preventing mistake and limiting movement.

[0056] In one optional embodiment, the inner liner 140 includes an inner liner frame 145, an inner liner body 146, a backstop 141, and a milk separator film 147. The inner liner body 146 is fitted over the inner liner frame 145. The backstop 141 and the locking platform 144 are both disposed inside the inner liner body 146. A clearance groove 142 is formed on the inner liner body 146, and a slide 143 is disposed on the inner liner frame 145. The inner liner frame 145 is used to support and position the inner liner body 146 to increase the structural strength of the entire inner liner 140 and prevent the inner liner 140 from deforming under negative pressure during milk expression.

[0057] Furthermore, the anti-reverse buckle 141 is ring-shaped and is used to surround the nipple, and always maintains a close fit with the breast during use to prevent milk from flowing back out and improve the user experience.

[0058] Preferably, the milk separator 147 is disposed inside the inner liner body 146, and a front cavity 148 is formed between the milk separator 147 and the suction bowl 120. The front cavity 148 enables the suction bowl 120 to quickly form negative pressure during deformation, thereby improving milk suction efficiency. The milk separator 147 can also block the milk to prevent it from splashing onto the suction bowl 120.

[0059] Specifically, the milk separator 147 has a vent 149, which is connected to the front cavity 148. When the suction bowl 120 undergoes elastic deformation away from the inner liner 140 under the suction force of the suction mechanism 160, the volume of the front cavity 148 increases and a negative pressure is formed, so as to draw air from the inner liner body 146 through the vent 149, thereby creating a negative pressure in the inner liner body 146 and drawing out the milk.

[0060] In one alternative embodiment, the strength of the inner liner skeleton 145 is greater than the strength of the inner liner body 146. Preferably, the inner liner body 146 is made of silicone material, and the inner liner skeleton 145 is made of hard silicone, plastic, or metal material, which has high strength and can effectively support and position the inner liner body 146; the inner liner body 146 and the milk separator 147 are integrally formed, and preferably, the milk separator 147 is made of silicone material.

[0061] Specifically, during the operation of the wearable breast pump 100, the wearable breast pump 100 is first put on so that the bra 110 and the inner liner 140 are both in close contact with the breast (the inner liner 140 covers the areola), and the nipple is inserted into the inner liner 140; then the suction mechanism 160 is activated to extract the air from the breathing cavity 170, creating a negative pressure within the breathing cavity 170. This causes the suction bowl 120 to elastically deform away from the inner liner 140. At this time, because the inner liner 140 is tightly fitted to the breast, a negative pressure is created within the inner liner 140, thereby drawing out milk. The milk flows downwards under gravity and enters the storage cavity 180 through the one-way guide 130, thus storing the milk. During this process, due to the one-way guide 130, the milk in the storage cavity 180 will not flow back, ensuring the reliability of milk expression. After one expression is completed, the suction mechanism 160 is paused. At this time, the suction bowl 120 will spring back to its original position under its own elasticity and draw outside air into the breathing cavity 170. The air in the liner 140 will also return to normal air pressure, and no more milk will be expressed. This cycle repeats until the milk expression operation is completed.

[0062] The wearable breast pump 100 provided in this embodiment of the invention includes a bra 110 comprising an integrally formed connecting ring 111 and a fitting cup 112. A suction bowl 120 is disposed at the end of the connecting ring 111 away from the fitting cup 112 and is integrally formed with the bra 110. The bra 110, suction bowl 120, and milk bowl 150 together form a breathing cavity 170. A suction mechanism 160 communicates with the breathing cavity 170. The milk bowl 150 and the bra 110 together form a storage cavity 180. The suction bowl 120 is used to elastically deform under the suction force of the suction mechanism to create a negative pressure inside the bra 110 and draw out milk. A one-way guide 130 is used to allow milk to flow into the storage cavity 180. Compared with the prior art, the wearable breast pump 100 provided by this invention simplifies the assembly and disassembly process, saves time and effort, improves assembly and disassembly efficiency, facilitates milk expression and disassembly for cleaning, and enhances the user experience.

[0063] Second Embodiment

[0064] Please refer to Figure 7 This invention provides a wearable breast pump 100. Compared with the first embodiment, the difference in this embodiment is that the suction mechanism 160 is external.

[0065] In this embodiment, the milk bowl 150 no longer has a notch 154, and the suction mechanism 160 is no longer embedded in the notch 154, but is externally placed in the milk bowl 150. Specifically, the milk bowl 150 includes a bowl body 155 and a back cover 156. The bowl body 155 and the back cover 156 are detachably and sealed together. The breast shield 110 is connected to the bowl body 155. The bowl body 155, the back cover 156, the breast shield 110, and the suction bowl 120 together form a breathing cavity 170.
